New personnel of 163 arrived at the fire Saturday night, increasing the total number of firefighters working the blaze to 317.

The fire, which ignited on Wednesday east of the Spanish Peaks, is now 10 percent contained. This is the first reported containment since the fire started.

Huerfano County was under a Red Flag warning from 10 a.m. to 8 p.m. Saturday which led to active fire behavior for much of the afternoon and night.

“The weather made it tough to fight the fire today,” Amy Daniels, a public information officer for the fire, said. “The unknown wind patterns make things difficult.”

Firefighters spent the day Saturday constructing and tying in existing lines around the fire perimeter to try and get some containment.

Structure protection remained a priority for firefighters throughout the day.

The fire was moving south to southwest and is approximately 10 miles southwest of Walsenburg.

Air tankers and helicopters continued dousing the fire with fire retardant and water.

Resources continue to be ordered and are arriving daily.

The Rocky Mountain Incident Command Type II team was assigned to the fire at 6 p.m. Friday.

Officials determined Saturday that the cause of the fire was lightning, according to Daniels.

The animal shelter at the La Veta Fairgrounds closed Saturday night due to a lack of need. Owners of small animals may take them to Noah’s Ark in Trinidad if needed.

Smoke from the fire picked up along the east Spanish Peaks as the day progressed.

Residents of Walsenburg and La Veta went about their days normally as many were seen outside riding bikes, eating ice cream and walking around town.

Mandatory evacuations remain in place for the Blackhawk Ranch subdivision, the Silver Spurs subdivision, from Walsenburg south to the Huerfano and Las Animas county lines and everything east of La Veta to Interstate 25.

An estimated 300 properties are within the evacuation area, according to a press release from East Peak Fire officials.

On Wednesday, 177 Boy Scouts were evacuated from the Spanish Peaks Boy Scout Ranch. A building on the ranch was destroyed, according to officials.

Nine structures and four out buildings have been lost in the blaze.

No injuries have been reported.

The Bull Gulch Fire burning in Fremont County is now 80 percent contained.

The acreage of the fire changed from 150 acres to 76 acres due to better mapping.

Pre-evacuation notices put in place on Wednesday for about 30 residences have been lifted.
